Billy Joel married his wife, chef Katie Lee, in 2004 when she was just 23 years old and he was 54. She was only five years older than his daughter, Alexa Ray, who was the maid of honor at the wedding.

It’s not that surprising that Joel’s wife is now said to be fed up with her boozing husband, who is more than old enough to be her dad. Katie hosted Bravo’s “Top Chef” in 2006 and has made appearances on Martha, Today, and Iron Chef. She’s growing up and says “If that’s movin up then I’m movin out.”

“The marriage has turned into a nightmare for her – she misses her young friends, and she’s bored with Billy,” says an insider.

“When she first met him, she was an innocent kid – but she’s grown up and her friends say she thinks it’ts time to move on.”

In a revealing snub, she took off during her husband’s May 9 birthday, divulged the insider.

“Katie went out with her friends on Billy’s birthday. She rarely goes on the road with him, and he’s lonely.

The article goes on to say that Joel sold the sprawling $37 million mansion in Long Island that he loved because Katie said it was too big for her. They now live in a $6 million townhouse in Manhattan.

Joel was in rehab for alcoholism just five months after they were married. He spent 30 days at the Betty Ford Center.
